BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a wearable electronic device, and moreparticularly to a wearable electronic device with a detachable powerunit.

2. Description of the Prior Art

With the expansion of the application range of wearable electronicdevices, the function is becoming more and more powerful, and the usetime continues to grow, however, the acceptable size and weight of thebattery in the wearable electronic device are often limited, thuslimiting the capacity of the battery. As a result, the battery capacityof the wearable electronic device is often unable to meet the needs oflarge or long periods of use. In the face of this situation, thewearable electronic device must use external power source to replenishthe electricity in order to continue to perform the function.

There are two kinds of external power sources: fixed (wired) powersupply and mobile (portable) power pack. Fixed power supply includeswall outlet and electronic equipment with USB and Lightning™ port, suchas, desktop computer, notebook computer, tablet computer and so on.Lightning™ is the exclusive transmission interface specificationdesigned and manufactured by Apple Inc. Mobile power pack is usually arechargeable secondary battery. The fixed power supply can be chargedonly when the wearable electronic device is removed from the user. Asfor the mobile power pack, although it can be carried with you, it canonly be placed in handbags, backpacks, travel bags and other personalbelongings. When needed, it can be taken out and connected to thewearable electronic device through a connecting line. It can not bedirectly attached to the user to transmit power to the wearableelectronic device, so it is not convenient to carry and use the mobilepower pack.

On the other hand, since the wearable electronic device is widely usedfor health management, such as, detecting heart rate, blood pressure,blood oxygen, sleep state, and so on, it is necessary to be worn fornearly 24 hours for continuous detection. However, for safety and otherfactors, the wearable electronic device must be removed when chargingand cannot be detected during charging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1A and 1B, a wearable electronic device 100 inaccordance with a first embodiment of the present invention comprises abody 101 having a first battery 110 to supply the power required for theoperation of the body 101. The body 101 also includes a port 111 and twojoint portions 112. The port 111 is disposed at the bottom of the body101 and is electrically connected to the first battery 110. The jointportions 112 are formed at both sides of the body 101. The function ofthe port 111 and the joint portions 112 is left to be described later.

The wearable electronic device 100 further comprises a band 102 forattaching the body 101 to a user. The band 102 may be made into a longstrip by materials such as fluoroelastomer, leather, nylon ribbon, etc.,so that the band 102 is flexible and surrounds the wrist, arm, chest,waist, leg, neck or head of the user. Both ends of the band 102 useknown techniques, such as magnets, buckles, Velcro™ etc., so that thewearable electronic device 100 can be removably attached to the user.Since the technique of combining both ends of the band 102 with eachother is conventional, it is unnecessary to further explain.

The band 102 has a bearing area 120 in the middle of its length to loadthe body 101. The middle of the bearing area 120 is defined with anaperture 121, which enables a sensor 113 carried by the body 101 todetect the heart rate, blood pressure, blood oxygen, sleep state, etc.,of the user through the aperture 121, so that the user do not need towear other external sensors for health management.

The band 102 also includes two wings 122 connected to both sides of thebearing area 120. A free end of each wing 122 is formed with a joint 123that is engaged with the joint portion 112 of the body 101. The jointportions 112 shown in the figure are dovetail grooves, so the joints 123are dovetail joints, which are combined with each other by tenontechnology, and other known techniques, such as pin joint, may also beused, without the limitation of the embodiments of the accompanyingdrawings.

The band 102 further includes a connector 124 and a set of firstconductors 125. The connector 124 is disposed on the bearing area 120and is connected to the port 111 when the body 101 is properly installedin the bearing area 120, so as to make the body 101 electricallyconnected to the band 102. The first conductors 125 are disposed on theband 102 and are electrically connected to the connector 124. The port111 and the connector 124 shown in FIG. 1B are illustrated by Garmin®commodity exclusive transmission interfaces, and other types oftransmission interfaces can also be used, without the limitation of theembodiments of the accompanying drawings.

Another important part of the invention is that the wearable electronicdevice 100 includes a belt 103 that is a detachable power unit havingone or more second batteries 131, an input port 130 and a set of secondconductors 132 electrically connected to the second battery 131. Thesecond battery 131 is flexible to be bent along with the belt 103, or,as shown in the figure, the belt 103 can be freely bent without theinfluence of the second battery 131 by using a plurality of non-flexiblebatteries. The input port 130 is used to connect an external powersource, such as, wall outlet, mobile power pack, or another electronicdevice, such as, desktop computer, notebook computer, tablet computer,smart phone, and so on, so as to charge the second battery 131. Thesecond conductors 132 are disposed on the belt 103, and the firstconductors 125 and the second conductor 132 have mutually attractivemagnetism, or make a snap button that can be fastened to each other, sothat the belt 103 can be removably attached to the outer surface of theband 102. At the same time, an electrical connection is generatedbetween the band 102 and the belt 103. The electricity of the secondbattery 131 is transmitted to the first battery 110 through the secondconductor 132, the first conductor 125, the connector 124 and the port111, so as to replenish the electricity consumed by the first battery110 and improve the endurance of the wearable electronic device 100.Moreover, when the belt 103 is removed, the power consumed by the secondbattery 131 can be replenished by an external power source (not shown)connected to the input port 130, so that the wearable electronic device100 can still be worn for 24 hours while charging, regardless of thesite and no time limit, at any time to master the information. Otherdesigns in which the belt 103 can be freely assembled to anddisassembled from the outer surface of the band 102, and the electricalconnection can also be adopted, are not limited by the magnet or thesnap button.

The belt 103 further includes an output port 133 electrically connectedto the second battery 131, so that the second battery 131 cansynchronously or separately supply power to another electronic deviceconnected to the output port 133, such as, smart phone, smart watch,etc., when the belt 103 is removed. The body 101 may also transmit datawith another electronic device via the output port 133. The input port130 and the output port 133 can be any type of transmission interface,such as, USB port, mini USB port, micro USB port, Lightning™ port,miniaturized Lightning™ port, and so on.

In addition, as shown in FIG. 2 (second embodiment), a wearableelectronic device 100 a comprises a body 101 a having a magnetic port111 a, and a band 102 a includes a magnetic connector 124 a, so as toreplace the port 111 and the connector 124 of the first embodimentrespectively.
